【国外标准】 Standard Specification for Self-Adhesive Polyester Fabric Reinforced Polymer-Modified Asphalt Steep Slope Roll Roofing Surfaced with Mineral Granules

This specification covers prefabricated, self-adhesive, polyester fabric reinforced, polymer-modified asphalt surfaced roll roofing products, with granule surfacing, designed for steep slope applications. These products use polymer modifiers in their top and bottom coatings and have an adhesive bottom layer which is exposed by removal of a peel-away protective release paper or film sheet. The specified tests and property limits used to characterize the sheet materials are intended to establish minimum properties. The minimum physical properties required for the sheet include thickness, peak load, elongation, tear strength, adhesion to plywood, side lap integrity, thermal stability, and granule loss.1.1 This specification covers prefabricated, self-adhesive, polyester fabric reinforced, polymer-modified asphalt surfaced roll roofing products, with granule surfacing, designed for steep slope applications. These products use polymer modifiers in their top and bottom coatings. These products have an adhesive bottom layer which is exposed by removal of a peel-away protective release paper or film sheet.1.2 The specified tests and property limits used to characterize the sheet materials are intended to establish minimum properties. In-place roof system design criteria such as fire resistance, field strength, impact/puncture resistance, material compatibility, uplift resistance, and others, are factors beyond the scope of this material specification. Factors regarding the suitability of specific roof constructions or application techniques are beyond this scope.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
